Celebrity Week In Review: Taylor And Harry Split, Matthew Debuts New Body And More (PHOTOS)

Welcome to splitsville.

At least that's what celebrity news consisted of this week as two of Hollywood's hottest young couples officially called it quits. First, on-again-off-again lovebirds Justin Bieber and Selena Gomez broke up for the second time and then Taylor Swift ended things with Harry Styles just two months after they started dating.

Now that's rough.

Also this week Matthew McConaughey, who shed almost 50 pounds for his role in "Dallas Buyers Club," revealed he has gained back 25 pounds! Ladies, Matty's abs are on their way back! (Thank goodness).

Speaking of abs, have you seen Mariah Carey's? She flaunted her killer frame in a red hot bikini in Australia.

Plus, Rosie O'Donnell welcomed a baby girl, pregnant Kim Kardashian took her baby bump (and baby daddy) to Paris, Brooke Burke revealed her post-surgery scar and Miranda Lambert lashed out on Chris Brown ... again.

Check out the best photos from the week below:
